The thoracolumpleural and dorsal puncture training model is a highly realistic teaching device used for clinical skills teaching and practical training, mainly for simulating clinical operations such as pleural effusion and pneumothorax. The model is designed based on the real proportion of the human chest and back. The epidermis is soft, and the muscle layer and rib structure are clear, which can truly reproduce the feel and resistance during puncture.

In the teaching process, trainees can practice the key steps such as the correct site selection, needle insertion Angle, depth control and drainage tube placement for thoracentesis through the model, and become familiar with the entire operation procedure. The model can be equipped with a simulated thoracic fluid system inside, enabling the operator to obtain realistic fluid reflux feedback after successful puncture, thereby enhancing the accuracy of clinical judgment and operation.

This model is widely applied in medical colleges and universities, clinical skills centers and nursing training, which not only ensures teaching safety but also avoids the risks brought by practicing on patients. Through repeated training, learners can effectively master the standardized techniques and emergency handling capabilities of thoracentesis, providing a solid practical foundation for future clinical operations.
